The paper considers the use of arsenic organic compounds as selective sorbents for the separation and analysis of complex organic mixtures. Based on the chromatographic factors of polarity, it was found that the studied sorbents range is characterized by high hydroxyl selectivity of the analyzed sorbates separation, due to the arsenyl oxygen presence in the structure of their molecule, which has an unshielded electron pair. It is shown that the functional substituents in the structure of the arsenic sorbents molecule have a direct effect on the chromatographic factors of polarity, the values of which increase when the functional substituents in the the phenyl ring (para-position) are introduced into the structure of the molecule. It was found that relatively low values of the chromatographic polarity factor (x) are observed for benzene, which also increases in the para-position of the ring. Based on the five-dimensional space and projection on the plane corresponding to the chromatographic factors of polarity, arsenic sorbents with extreme characteristics that have higher chromatographic factors of polarity (y) in comparison with known analogues were identified. Based on the conducted research, it was found that arsenic sorbents show high separation selectivity of aliphatic alcohols from hydrocarbons. Thus, when developing specific methods for the analysis of complex alcohol-hydrocarbon mixtures, we propose to use arsenic compounds as selective sorbents intended for the separation and analysis of substances capable of forming intermolecular hydrogen bonds under gas-liquid chromatography. At the same time, their retention times are higher than similar characteristics of non-polar compounds. This allows you to separate the analyzed components with close retention times.

The changes in energy and photoionization spectra of atoms upon confinement by a spherical environment are explored theoretically. Two kinds of confinement are considered: an endohedral confinement, such as inside the bucky-ball C 60, and an impenetrable spherical confinement of adjustable radius. We demonstrate modifications in the energy spectrum and electron correlation effects in confined atoms, the appearance, nature and origin of "confinement" resonances in photoionization spectra of such atoms, as well as new regularities in the periodic table for "compressed" atoms. These findings are of importance for basic and applied physics and chemistry of atoms, molecules, surfaces, etc.
